plugin problem

i’ve been using am’s kicklab xl for a while and i’m experiencing a problem. the first few times i play my project the plugin works, but eventually when i load up the plugin later on there is no sound coming from the track which is strange because the leds show that there are midi notes playing, but again i don’t hear the kick on the track. anybody know what i can do about this?


Isn’t it Trial version of the plug-in?

no. it’s a free vst.
